Fair enough. Is there any way to handle this error and return a false?
(People frequently ask "how can I check to see if a table exists", and not
all interfaces handle errors the same way, but everyone should know how to
deal with a table result, so that we can provide a 7.3 version of "SELECT 1
FROM pg_class where relname='xxx'".
Thanks!
